Estimated costs of tuberculosis services in Brazil, 2023.
Article in BMJ open respiratory research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionTo eliminate tuberculosis (TB) in Brazil, scaling up screening and prevention strategies will be essential. We estimated costs of TB services in Brazil to support budgeting, cost-effectiveness analysis and inform the implementation of these strategies.
methodsWe leveraged databases from five large cities in Brazil (Manaus, Recife, Porto Alegre, São Paulo and Rio de Janeiro) to estimate costs of TB services in 2023 US dollars. We estimated mean costs and 95% uncertainty ranges (95% UR) for specific components and combined these components according to national algorithms for TB diagnosis and treatment in adults and children to estimate costs for different services. We leveraged these outputs to estimate the costs of household contact investigation.
resultsWe estimated the mean (95% UR) cost of testing children for TB infection with a tuberculin skin test (TST) or interferon-gamma release assay and providing 3 months of once-weekly isoniazid and rifapentine (3HP) was US$48 ($25-$82) and US$67 ($43-$101), respectively. Providing 6 months of treatment for drug-susceptible tuberculosis (DS-TB) to children was US$557 ($163-$1195). In adults, costs were similar to the cost of TST and 3HP costing US$49 ($25-$86) and 6 months of DS-TB treatment being $583 ($175-$1252). For both children and adults, costs of newer, 6-month treatment regimens for rifampin-resistant tuberculosis (RR-TB) were less expensive than 18-month regimens. In children, the cost was US$4807 ($1559-$10 066) for the 6-month regimen and US$9212 ($2756-$19 567) for the 18-month regimen. Corresponding costs in adults were US$3518 ($1169-$7330) and US$7910 ($2533-$16 717). Across 10 000 households with an index TB patient, we estimated use of a TST and 3HP for TB infection screening and treatment and 6-month regimens for DS-TB and RR-TB disease to cost $1 093 531 (95% UR $409 349-$2 217 054).
conclusionThere are important cost differences in TB services depending on diagnostic and treatment choices. These data are essential inputs for budgeting and cost-effectiveness.
